Unselecting Data List in custom component

Hi,
I am trying to make a dropdown menu. I've followed instructions here: http://cookbooks.adobe.com/post_Creating_a_custom_combobox_component_using_Flash_C-17234.h tml and it works well but there is a problem.
Here's what I did.
Created a custom component with 2 parts. Toggle Button and Datalist. then I set up the states appropriately. When I select a specific item on the datalist, I go to a different screen state but I share that button across the states (it's basically a menu option). That part works great.
Here's my problem:
On my datalist, I have a "on select" event which takes me to the right screen state. However, When I come back to that component, the datalist still has that item selected.
Is there a way to "deselect" something on the datalist when I move from one state to another? Or to force the selectedIndex to be -1 whenever the datalist appears?
Thanks!
- Jana

In which part of the timeline did you add this action? Inside the datalist? I don't see the property "selected index"

Hi Everyone,
                I am new to Flex soo pardon me if my questions are quite basic. I have searched a lot before posting here, might be I was not looking in the right direction. Please redirect me to the path that leads to the solution of the problem. I really appreciate any help that I can get.
I'm followiing this video tutorial.
http://www.gotoandlearn.com/play.php?id=100
All was going fine, until the tutor wanted to add custom component in the application. He added the HBox which I couldn't find in Flash Builder 4.6 so I added HGroup instead in my new component. Now when I want to use the data that was fetched in the parent component in custom component it gives me error. Here is the code and their file names.

What needs to be done to use the item renderer right in custom component ? Please tell me the solution to it... I'm stuck on it for quite a few time.
Thanks

Hello Ravi,
one option is the create a public attribute to share your value note data with other components.
Another option is a function group with two function modules "SET_" and "GET_".
I´m sure one of the webclient UI Gurus here in this forum could share less "dirty" ways with you.
Kind regards

Custom component data binding

Hey people,
I'm trying to write a custom component which extends from JPanel (has a List<?>). It will basically display some sub-panels on itself by considering the underlying data (database table rows). I want to have the same functionality with JTable binding. I'm having difficulty listening changes occur on the list. How can I listen to changes inside the list in my JPanel component? Should I write a custom model? or Should I use a ObservableList? any suggestions are welcome..

Actually, it's not a JList. My component is a custom JPanel which has an underlying collection to hold data. I'm binding this underlying collection to an ObservableList which is filled with the result set fetched from the database. It's a standart ArrayList<?> and I want to listen to the changed that made to this list.
MyPanel extends JPanel {
private List<Person> list = new ArrayList<Person>();
}I'd like to see any changes made to the list inside MyPanel class.

Create a Report with InfoPath to Show Only Some of Data in a Custom List

I have to create a report using InfoPath from a SharePoint 2010 custom list.
The report has 8 columns, and there will be four repeating? tables in it, each table including data that is filtered from the bigger list to meet two criteria. All the items in all four repeating tables will meet one of the criteria (Type of Task field
= Human Capital) and each of the other four repeating tables will be different depending on the contents of the Personnel Action Location field. Neither Type of Task or Personnel Action Location will be columns in the repeating tables.
How can I filter data from a custom list as it goes into a form?
Can I do this on fields that don't otherwise appear in the form?
If I can just figure out how do to one form, we can do many, many more, and finally really move over to SharePoint, but I just need to get the first one figured out please. Thanks!

Hi,
If you would like to connect data to InfoPath form from SharePoint list, you could make use of Data Connection. You could locate it via InfoPath form > Data ribbon > Get External Data > From SharePoint List.
And here are the links to use it for your reference:
Add a query data connection > Step 1: Add a secondary data connection

Custom component accessing data

I am trying to build a custom component that utilizes the
datagrid. I want to create a class that loads in xome XML and
populates the datagrid. The datagrid's ID is not available in the
class's load.COMPLETE event handler, so I cannot populate the
datagrid from the class. I then tried making a public property in
the class that holds the XML, but, still I run into problems,
because that property is null before the XML is loaded, so I cannot
access it outside the class until the load is complete anyways. So,
I guess the question is, what would be the best practice for
passing data, loaded from a class, to a custom component.

Events.
There are some examples in the archives.

Problem with inputText in my custom component

Hi, I have a custom dataTable component that I'm trying to get to work. It has to be a custom component because dataTable doesn't support rowspan, colspan, multi line headers, and a rendered attribute for rows. The problem is, that when I wrap the column tag inside my row tag then the method for the inputText tag never gets called in the UPDATE_MODEL_VALUES phase.
I'm starting to think that JSF doesn't support 2 levels of tags between the inputText and dataTable. I'm hoping that someone can tell me what I have wrong with my components.
Here is the JSP snippet.
<cjsf:rptTable>
     <cjsf:data id="dataTable1" value="#{allAuthUser.tableRows}" var="myTableRow1">
          <cjsf:row>
               <cjsf:col>
                    <h:inputText id="tableTestFld" value="#{myTableRow1.testFld}" size="5" maxlength="5"/>
               </cjsf:col>
          </cjsf:row>
     </cjsf:data>
</cjsf:rptTable>Here is what it renders. It looks to me like everything renders fine. So I'm guessing that there is something in a component that is causing JSF during the life cycle to not be able to process correctly.
<table>
     <tbody>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_0:tableTestFld" name="tblmaintForm:body:dataTable1_0:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_1:tableTestFld" name="tblmaintForm:body:dataTable1_1:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_2:tableTestFld" name="tblmaintForm:body:dataTable1_2:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
     </tbody>
</table>Note: If I leave off the row tag it renders the same way except of course the <tr> and </tr> tags are missing. If I do this, then the backing method for the inputText tag is called and everything works fine. Why doesn't it work with the row tag in place?
Here are the components:
public class UIRptTable extends UIComponentBase {
     public UIRptTable() {
          setRendererType("tblmaint.rptTableRenderer");
     public String getFamily() {
          return "javax.faces.Output";

Hi, Ray!
1) I was trying to put a button in the column header (for sorting) and I couldn't get that to work. That involved the >colhdr tag. I got that to work but I don't remember the fix. I'll look it up and reply back with that when I can.Dealing the first part of your trouble, you need NOT a custom component.
I have looked through the implementation of RepeaterRenderer, as you advised me, and found that the multi-header possibility is included in the implementation of dataTable control.
The code below is the part of source of repeater.jsp with only change:
<d:data_repeater>  <h:dataTable>
And it works fine.
<h:dataTable id="table"
binding="#{RepeaterBean.data}"
     rows="5"
value="#{RepeaterBean.customers}"
var="customer">
<f:facet name="header">
<h:outputText value="Customer List"/>               <!� First Header row -- >
</f:facet>
<h:column>
<%-- Visible checkbox for selection --%>
<h:selectBooleanCheckbox
id="checked"
binding="#{RepeaterBean.checked}"/>
<%-- Invisible checkbox for "created" flag --%>
<h:selectBooleanCheckbox
id="created"
binding="#{RepeaterBean.created}"
rendered="false"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Account Id"/>               <!�Second Header row -- >
</f:facet>
<h:inputText id="accountId"
binding="#{RepeaterBean.accountId}"
required="true"
size="6"
value="#{customer.accountId}">
</h:inputText>
<h:message for="accountId"/>
</h:column>
<h:column>

Custom Component Error -- Uggh

I have tried to solve the problem using online resouces, 3rd party message boards, Xcelsius tutorials, the textbook "Xcelsius 2008: Dashboard Best Practices", tutorials which came with the Xcelsius SDK, among others, however, I continue to run into problems. Additionally, I am have tried to fix by reading the Flex 3 SDK, Xcelsius 2008 SDK, and the samples for Xcelsius/Flex which came bundled in the SDK.
The problem is that the custom component, created in Flex 3 Hotfix and brought into Xcelsius using the Add-on Packager and the Add-on Manager does not display on the canvas. While all of the inherent components in Xcelsius work correctly the custom component does not display. When dropped on the canvas it simply disappears and never instatiates on the canvas and also is not listed inside the object browser. The custom component is, however, listed in the vertical menu under the category Add-Ons.
Example:
1. I use a sample Flex project which was included in the Xcelsius SDK and bring it into Flex 3 builder.
2. I configure the project to run appropriately in my local environment
3. I build the project successfully.
4. I open the Xcelsius Add-on Packager
4a. In the GENERAL tab I give the package a name
4b. In the VISUAL tab I type the name of the class (i.e. com.business.dept.project )
4c. In the VISUAL tab I type the display name (i.e. Email Component)
4d. In the VISUAL tab I type the directory location of the .swf (i.e. C:\Xcelsius\Flex\Project\Email\emailcomponent.swf )
4e. In the VISUAL tab I type the directory location of the property sheet (i.e. C:\Program Files\Business Objects\Xcelsius\SDK\bin\propertyinspector.swc )
4f. In the BUILD tab I build the component sucessfully
5. I open Xcelsius and go to File -- Manage Add-Ons
6. I add the new emailcomponent.xlx file to the Add-on Manager and select Close
7. I exit Xcelsius and reopen Xcelsius
8. The new component is listed in the vertical menu under Components -- Add-Ons
9. I test the function of inherent objects and drag a pie chart successfully onto the canvas of Xcelsius
10. I drag my new component onto the canvas, and while there is a visible border outline of the object as I drag over the canvas, when I drop the component onto the canvas the object does NOT appear on the canvas.
11. I re-test another inherent componet in Xcelsius which works fine
12. I re-test my component with the same failure.
Thank you for the assistance in advance.

I have successfully created a Flex component in Xcelsius. The data is static and hard coded into the Flex component which is not ideal, but it certainly is a step in the right direction.
My steps were as follows:
1. Create a new Flex project
2. Create a new Flex component and save it into the class namespace directory I was planning on using
3. Include all of the MXML logic for the application in the component file
4. Reference the component file in the Application file as a namespace reference
5. Save the file
6. Create an .xlx file using the Xcelsius Add-on Packager
7. Typing the class namespace location using the entire path and file name without the extension
8. Loading the new component into Xcelsius
9. Building the app.
Success.
Thank you for all the help

Unable to Edit the View in Custom Component

Hi Experts,
Please help me to resolve this issue !
I am unable to lock the BOL Entity in my custom component using BTAdminH. I have written the below code in the Edit event Handler for Edit Button. The lr_entity->lock( ) condition statement is getting false and it is skipping the "set_view_editable( me )." code statement. Why??
This is code excerpt that I have taken from edit button of the BP_HEAD/AccountViewSet and altered to my component/View
DATA: lr_entity     TYPE REF TO cl_crm_bol_entity,
        lr_controller TYPE REF TO cl_ZVKH8_bspwdcomponent_impl.
TRY.
      lr_controller ?= me->comp_controller.
      lr_entity ?= lr_controller->typed_context->btadminh->collection_wrapper->get_current( ).
IF lr_entity IS BOUND.
IF lr_entity->IS_LOCKED EQ abap_false.
    IF le_entity->IS_CHANGEABLE EQ abap_true.
       IF lr_entity->lock( ) EQ abap_true.
        me->view_group_context->set_view_editable( me ).
       ENDIF.
    ENDIF.
ENDIF.
ENDIF.
and when I directly executed the below code in the Edit event Handler for Edit Button I am receiving the dereferencing NULL value exception. Why in my custom component in many places this happening??
me->view_group_context->set_view_editable( me ).
Exception Details
CX_SY_REF_IS_INITIAL - Dereferencing of the NULL reference
Method: ZL_ZVKH8_DETAILSEF_IMPL=>EH_ONBACK
Thanks,
Bujji

Hi Summit & NishaNC,
Thanks for your responses !
As suggested, I have debugged the code for ->lock( ) method and there are exceptions raised from some methods.
Method GET_LOCK () -> Method GET_ROOT () ->Method GET_PARENT ()
At GET_ROOT( ) method i have received an exception
"Root entity BTAdminH could not be determined" and one more "Entity BTAdminH could not be locked"
Later when I have checked in MODEL Browser, I found that the BOL object "BTAdminH" for my view is an Access object and not the Root Object.
Hence, I have a question? Does the locking can be done only for ROOT Objects?
If this is TRUE then I think this is the major problem with my custom component where even the cross component navigation is also not happening and in many places I am receiving "Dereferencing NULL Value" information.
Also I have gone through some of the Threads and one information that I found from Sumit Mittal
1. An access object is an independent entity, has primary keys of its own.
2. A root object is a special access object that is at the top of the hierarchy based on business rules.
3. A dependent object's primary keys are supplied by access objects and it's lifetime is bound to them. If the parent object is destroyed, the dependent object is also destroyed.
4. Search objects are query objects useful for querying root objects
5. Search result objects - Search objects return the results in the form of a result object together with a relation pointing to the root object.
6. View objects - ?
7. Dynamic search objects - Used in advanced search, supports ranges and operators
Could you please specify in which scenarios we have to go for Access Objects and Root Objects
Thanks,
Bujji

How do you reference a valueObject located in main to a custom component created in Catalyst?

Hello,
I have been working with the Catalyst Beta 2 / Flash Builder beta trying to create a photogallery and have hit a little bit of a snag, try as I might I can't seem to find the answer anywhere. I am still new to Flex so please excuse me if this is a basic question, I have been trying to understand more about Flex to make my designs in Catalyst better.
I found this video on Adobe TV: http://tv.adobe.com/watch/rich-internet-applications-101/ria-stepbystep-16-binding-a-data- service-to-flash-builder-components/
It's wonderful and I have the datalist I created in Catalyst working with the XML file I generated but I designed my little photogallery a bit diffrent, I created a Custom Component in Catalyst so that when you click an item on the DataList it pop's up a little screen with a larger photo in on it, rather then having an image in the main application. Now my problem seems to be that I can't refrence the valueObject I created with the wizard as it's in my Main.mxml file, is there a way to refrence it from my Custom Component so the larger image will display? Is there a way to let the component know which item on the dataList in the main application is selected and display the correct image?
I should also say I really enjoy working with the Beta for both Flash Builder / Catalyst, thanks for the hard work!
Thanks for the help,
Chris

I am afraid you cannot bind to static properties in Windows Store Apps. It is simply not supported.
You could create a proxy class that exposes the static command property and bind to this property of an instance of the proxy object:
http://stackoverflow.com/questions/14186175/bind-to-a-static-field-in-windows-8-xaml
http://stackoverflow.com/questions/4708711/how-can-i-use-the-xstatic-extension-for-phone7-silverlight-apps
You will of course have to create an instance of the proxy object. There is no way around this.

Decode-method for custom component isn't called

Hi,
i have writen a custom component which gets some information by command-link. To make the data from the link accessible, i wrote a decode method in my renderer and in me component. But both method are not called from the faces framework.
Dows anybody knows what i made wrong???
Thanks, Sebastian

Hi,
thank you for your reply.
Unfortunately the processDecodes(...) of my component is also not called from the framework. Does anybody knows what i'm making wrong???
Thanks!

SSRS - Pass Field Value List To Custom Function Assembly And Display Result

I have written a SQL Server Reporting Services custom function as a C# assembly DLL and added it to my report. The purpose of the function is to search for outlier records in a collection of data. The data is represented as an array of floating point -tuplets
(float[][]). In a medical patient database, these might be things such as blood pressure, cholesterol, hight, weight, waist measurement, etc.
Several user input parameters are provided in the report, including numeric seed values for this particular algorithm. One multivalued parameter is a list of the numeric columns to be used as input to the algorithm because, importantly,
the user can choose any subset of the value columns. I have a tablix that will display columns from the dataset conditionally, based on which of those columns are chosen.
At this point, there are two issues I'm having difficulty with:
How do I, in the course of running the report, take just the numeric columns that the user has chosen (ignoring all others in the dataset) and pass them as a float[][] to my custom function? Or is there something in the
Microsoft.ReportingServices namespace that I should use to query an input dataset and convert it to an array in my C# code?
How can I present the array subset returned by my custom function in a tablix in the report?
Note: One thought that occurs to me is that outlier records tablix could be contained in a subreport, but I'm not clear on the logistics of passing dataset field results from a master report to a subreport.
I envision a final report when run to be similar to the following:

Hi Mark,
Sorry for the delay.
From your description, you want to pass the dataset data to a custom code array, and return the subset of the array, right? In this case, you can use a custom function to add the data to array, and use the a custom function to sort the data base on your
requirement and then use a function to get the subset of the array. Here are some sample custom code for your reference.
Add to arryay
Dim values As System.Collections.ArrayList=New System.Collections.ArrayList()
Function SetText(ByVal value As Integer) As Integer
    values.Add(value)
    return value
End Function
Sort array
Function Sort()
Dim i as Integer
Dim j as Integer
Dim t as Integer
Dim n as Integer=values.Count-1
For i=n To 1 Step-1
For j=0 To i-1
if values(j)<values(j+1) Then
    t=values(j)
    values(j)=values(j+1)
    values(j+1)=t
End if
Next j
Next i
End Function
Return value.
Function Rank(ByVal value As Integer)
   return values(value)
End Function
Assume that you pass [Weight] field to array, you can use the expression below on the Weight column:
=Code.SetText(Fields!Weight.Value)
Then use the expression below to get the values.
PatientID:=Sort() & Lookup(Code.Rank(0),Fields!Weight.Value,Fields.Patient.Value,"Dataset")
Height:=Lookup(Code.Rank(0),Fields!Weight.Value,Fields.Height.Value,"Dataset")
Weight:=Code.Rank(0)
Hope this helps.

Charlie Liao
